one side of a cube measures 0.53 cm. the mass of the cube is 0.92 g. what is the density of the cube
ziro4ka [17]

Answer:

6.17 g/cm³

Explanation:

Data given:

one side of cube = 0.53 cm

mass of the cube is 0.92 g

density of the cube = ?

Solution:

First we will calculate for volume the cube

As we know all the sides or edges of a cube are equal so volume equation will be

So,

    V = length x width x height

    V = e³

as on side = 0.53 cm

then

     V = (0.53 cm)³

     V = 0.149 cm³

Now we will calculate density of cube

To calculate density, formula will be used

             d = m/v . . . . . (1)

where

d = density

m = mass

v = volume

put values in above formula 1

                   d = 0.92 g / 0.149 cm³

                   d = 6.17 g/cm³

so. the density of cube = 6.17 g/cm³

Explain what helps convert non-rich oxygen blood cells back to oxygen rich cells?
Reil [10]

Answer:

As blood travels through the body, oxygen is used up, and the blood becomes oxygen poor. Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.
